[birt-charting-dev] Supporting timestamp

[Sheldon Lee-Loy <sleeloy@xxxxxxxxxx>]

I was looking at the APIs.  From
what I gather you can add blocks to the model.  These block can be
added the chart "block".  Therefore to render a timestamp
I add the following to the chart model:


    ChartWithAxes cwaBar =
ChartWithAxesImpl.create();

//Create timestamp label block
    LabelBlock timestamp =
(LabelBlock)LabelBlockImpl.create();
    Label label = LabelImpl.create();
    Text text = TextImpl.create(SimpleDateFormat.getInstance().format(Calendar.getInstance().getTime()));
    label.setCaption(text);
    timestamp.setLabel(label);

//Add timestamp to the chart model
    cwaBar.getBlock().getChildren().add(timestamp);


I was able to see the timestamp however,
the timestamp is displayed in the top right corner.  Is there a way
to layout the timestamp.  Are there any layout classes?

In terms of supporting timestamp features
such as date formatting I guess I could extend the LabelBlockImpl class
to add specific timestamp attributes for our needs.

Thanks,

Sheldon
